Fix timer.cancel action fires timer.cancelled event even on idle timers

[rrooggiieerr]

Breaking change

Technically I think this would be a breaking since this fix stops calling the timer.cancelled event on idle timers, however I think this shouldn't be called in the first place, hence this fix

Proposed change

This change stops the timer.cancel action to fire the timer.cancelled event when a timer is idle/already canceled.

I added an extra unit tests for testing canceling already canceled timers.

Also please see #134505 for some findings and thoughts I have on canceling and finishing paused timers.
